Oceanographic Survey in the American Samoa Exclusive Economic Zone (EEZ) (OES0602, EK60)
Oceanographic data were collected along five predetermined transects in the American
Samoa EEZ and consisted of CTD casts, trawl samples, and continuous current and EK60
recordings. CTD cats were conducted at predetermined stations. CTDs were equipped
with oxygen sensors and fluorometers. Trawl operations were conducted at predetermined
stations along the transects using a Cobb trawl at depths of the shallow and deep
sound scattering layers. Currents were continuously monitored using a RD Instruments
Acoustic Doppler Current Profiler (ADCP). Biological backscatter were recorded using
the EK60 echosounder system (38, & 120 kHz) along the transects.

Purpose | The scientific objectives of this cruise are to collect data on physical and biological oceanographic properties of the American Samoa EEZ where dynamic eddy activity is created by the interactions of the eastward flowing South Equatorial Counter Current and the westward flowing South Equatorial Current. Mesoscale eddy activity varies at different temporal scales and seems to affect catch rates of the albacore in the region. |
